Maple DNA Course

BERT, DNABERT, and encoder models

Why encoder models are a natural fit for DNA classification, retrieval, and embeddings.

Learning Objectives

What this lesson should make precise

01

Name the core abstraction and its failure modes.

02

Translate the concept into a Maple/Hermon proposal contract.

03

Define at least one evaluation case that can fail the model safely.

Tutorial Flow

How this lesson becomes a demo and training target

Each tutorial is written as a user education path and a model-improvement artifact. The diagram shows how the idea moves into a lab, a typed contract, an eval gate, and then a Hermon/MapleAI demo route.

01

Concept

Encoder objective

02

Applied Lab

Applied lab: BERT, DNABERT, and encoder models

03

Output Contract

model_family, tokenization, labels, confidence

04

Eval Gate

Does the answer separate model proposal from deterministic execution?

05

Demo Route

Maple DNA training and public model checks

01

Encoder objective

BERT-style models learn contextual representations by hiding tokens and predicting them from both left and right context. The result is an embedding useful for classification and retrieval.

  • Bidirectional context.
  • Masked-token training.
  • Embedding-first usage.

02

DNA adaptation

DNABERT applies encoder modeling to DNA-language tasks by representing sequence context. The output is not a lab protocol; it is a computational representation.

  • Classifier heads.
  • Embedding search.
  • Motif-style context.

03

Hermon DNA role

Hermon DNA should explain when to use an encoder, how to prepare safe computational inputs, and how to interpret labels under uncertainty.

  • Explain uncertainty.
  • Route to classifier.
  • Avoid wet-lab execution.

Lab

Applied lab: BERT, DNABERT, and encoder models

Design a safe DNABERT-style classifier workflow for labeling a toy sequence as storage-like, motif-like, ambiguous, or needs review.

Expected result

  • A typed JSON-style proposal rather than free-form advice.
  • Clear authority boundaries and denied operations.
  • A test or rubric that decides whether the proposal is deployable.

Evaluation

How Maple would grade this work

Rubric

  • Does the answer expose assumptions instead of hiding them?
  • Does the answer separate model proposal from deterministic execution?
  • Does the answer produce artifacts that can be tested, reviewed, and rolled back?

Output contract

model_family, tokenization, labels, confidence, safety_controls, receipt

Use this lesson as training direction

A strong lesson gives users a mental model and gives Hermon a sharper target for examples, probes, and demo prompts.
